I guess no ammonia yet.... Am travelling now and will be back Saturday, so thought not to add any fish till I get back and while I was away, the bloom happened...
What should I do now? Turn off the lights? Add a clown? Don't want damsel, scared it will just be too dominant...
Okay, the lights being on has contributed to a major algae outbreak. But the tank isn't cycled, as evidenced any a total lack of nitrates, so cant add any fish or CUC cuz They would just die. At the end of the cycle, ammo and nitrites should be zero, but nitrates should be high from the nitrogen that was converted by the ammo and nitrites.
I know you said you're traveling now, so hopefully the lights off while your gone. If not, is there someone who can turn it off?and if they would be so kind as to throw a couple of raw shrimp in there for you(i explain this below), that would be very helpful.
then the cycle can start while you're gone.
So turn the light off, not needed during cycle. And the blackout should help some of the algae die off, but that won't take care of it entirely.
You need to add an ammonia source to get the cycle started. It can be a couple pieces of raw shrimp or fish that you just toss in the tank and let rot. Or you can do liquid ammonia. The raw shrimp/fish method is easier cuz you don't have to dose everyday, but it can get smelly. The liquid ammonia smells better, but needs to be dosed everyday. The cycle can take weeks.
Let the shrimp rot, that's your ammonia source. Some people do fish-in cycles, but IMO
that's cruel cuz the ammonia burns their skin and gills and can kill then and then nitrites outcompete the oxygen in the water, so they can essentially suffocate and die. Then the nitrates, which is the least toxic, can still suffocate them at high levels. And by the end of the cycle, there will be high levels of nitrates. No fish needs to go through that suffering when you can just throw in a raw dead shrimp. I'm done with my lecture now. Haha.
Next you'll need to manually removed as much of the hair algae as you can by hand or using a siphon vacuum. I've heard of people using a new toothbrush to scrub the algae off the rocks.
When the tank has cycled, your first CUC members need to be ones that will eat hair algae, like turbo snails and an emerald crab.
